The Lowest Animal

Human nature is very interesting, over the years, humans have advanced mentally and in temperament, but also some have fallen short of improvement and reverted to a nature that is that of an animal. One thing about human nature that I'd like changed is the inability to get along. I know that prejudice is a staple of humankind and unmitigated peace among people in the world is a seemingly unattainable concept, I still think it would be ideal if people were to avert from hostility.
